To all whom it may concern:o

Be it known that I, Siiama'J. WiiN'rwoa'rn, a citizen of the United States, residing at Newport, in the county of Cam bell ccrtain new and useful Improvements in Shoe- Finishing Machines, of which the following is a specitication.

This invention relates to machines for tia- ,ialiing shoes andl is herein shown as einbodied in a machine for shrinking and ironing the uppers of lasted shoes to'perfect the appearance of the surface of, the stock and to take out, by smoothing and rubbing and I by the shrinking effect of heat, fullness of stock oieven wrinkles which may remain in the shoe when it comes to this finishing operat-ion.

An important .feature of this invention ia be reco ized in a working tool provided with an e ge shaped and arranged to engage the shoe upper in the crease between t e laat and the solo edge and a lace shaped to engage the upper on the aide ,of the last y2li above said ci-eiiseiand iiieai'iii for actuating said tool len tliwise of the crease to sha ie said engage( portions of he up r to tie underlying faces of the' last and tie edge of the shoe innergole. This featurtLQLthe iiiveiiti ui preteraliiy embodied 'in a tool having aconcave face to engage the'u per on the aide of the laat and a blunt ged flange in continuation of said face to extend into the crease between the-sole and u per u per connecting segni iio'aa to prevent injuipy to said seam by auch engagement with the aide-0f the shoe, aud means is preferably provided for actuating the tool in a direc- 40 tion appropriate to give a rubbing treatment to the work. By auch a tool so actuated these portions of a shoe can be aha with accuracy and rapidiiy'and the rub. ing ac# tion as the work progresses sete the stock in 45 the shape it acquires.' In accordance with a further feature of this invention Ieinplo au auch tool a heated upper shaping rol formed with an annular concave ironing siii-- face in ita riphery iihaped to receive the 60 convex sur ace of the toe portion of a shoe t said concave surface of the roll terminating at one end of the roll iii an overhangiii smooth faced lip to enter the welt crease o the shoe. This contour is of importance for -slioe without leavin far enough outwar y to be visible in and it enables one to reach'into the welt crease and finish the surface of the u per as far ae the upper will be visible-in e completed shoe. he work of auch an instrument, when heated, is of particular value becaue it ia about the curved edge of the shoe bottoni at the toe that it is most ditlicult to last the wrinkles that extend above t e welt crease. V l

I have discovered that the shrinking effect of-heat on upper leather of dry tannage is" veryl marked and that by, the use of the ent apparatus I am ena lcd very rapidi) than can otherwise be employed, thereby en@ abling me to shrink the leat er to a greater extent or more rapidly than can be done without such ingu-rial. Also the use of auch viacouL material enables me-t0 ytreatf'enameled leatlior the coatings of which are softened by the lient and would adhere to the bare tool. A further feature of this in vention is therefore to be recognized in means for applying viscous material to a heated roll und drivin the roll togrub and heat the upper and to istribute the vscou! material niitoniatiially over the surface of the upper engaged b the roll. The roll advantageously be oriiied with an ironing. surface that is extended from the concave resi y 05" improve the appearance of shoes, particul r 'lo annular surface above described into a com 05 vox annular poi-tion shaped to treat the top' face of the shoe, so that the several parte of the toelikely to require .treatmentcan be operated upon conveniently with one 'hand ing of uw um. 'rim described mi im ne the advnnta that the double curvature formed by tie two adiacent facea iyes .a contour, one |Iioitioit or another of w icl. iai adapted to a moet every part of the shoe that is to bc worked u on. mb

' A fin-ther feature' o this invention 'wlii is of practical importance is found in .thel provision for heating the working surfaces M4 ...wwwrun-na. mwen.. .man mi, imnaaiimiia- 'rni n n .Vmnamrmn-...aum-MIII. anniiMyIJnLmA-a mmm .n..nninan 'of the Iroll. These surfaces, as above dedotted lines in Fi it. The lroll also has a scribed, are mainly on the .peripher' of the fu roll and thefy mast bc kept sinoot lshed and o constant shape. 'I have rove rthcr ironing ace extended at the left ly polhand sideof the concave portion into a conx portion shaped to treat the top face of vided a heating means which is dcvoi of the shoe between the instep and the toe the usual objections to gas flames and steam wl heaters, both of which require outside quently nee 'sources of supply and also produce discozm to ierc the ipper tends to bridge and frc s to be shrunk to fit it down the contour of the last. It is to be noted fort to the workman in warm weather,'and that when the work is presented as in Fig. 2 which will adequately heat to the desired the tool is actuated lengthwise of the welt degree the peripheral working faces of the crease to .shape uniformlyall around the working end face against 'which is arranged of for frictional engagement a wooden block' .tool without in uring them. To this end I toe the en aged portions of the uplper to have formed t e rotary tool with e. nonthe underlying faces of the last and t e edge the innersole.

A particular advantage for this is ieatiiig means is found when t roll is coated with viscous material as conan a seat for a block of felt Il or the like ie ironing the front edge of which is shaped in accordee with the contour of the roll A. Above templated by this invention because it heats the 'block of felt is a receptacle l0 for visthe roll without danger of igniting such macous material such as thin vaseline or oil tei-iai or of rubbing it olf. wl The several features of this invention will pi' iich through a suitable duct flows or is esscd down to saturate the felt and cause be more fully understood from the following thc l.i.ter to keep the roll coated with the description of the illustrative embodiment viscous material which is thus automatically herein presented and will then be pointed distributed over the surfaces of the upper out iii the claims. h

Fre- ?uently the wrinkles extend across the top ace of the shoe, or vamp portion of the shoe, in which event. the convex portion of the iron is adapted to smooth out the wrinkles therein. [n turn shoes wrinkles are more apt to occur in the vamp portion than .with welt shoes and for this purpose the extended .portion of the iron shown in Iiig. 2 is highly desirable. ln turn shoes the iron is applied to the shoe after it luis been turnei and )laced on the last, and after the licei seat is astened by the laster. In other than turned work the iron shown in Fig. 5 has been found sul'lieent to inish and eoniplete the lasting of the shoe, making a complete and smooth tit of the upper.

Having explained the nature of this invention and described a preferred embodiment thereof, I claim as new and desire to secure by Letters Patent of the United Stateszw 1.
